25 Claims.

This invention relates to phonographs and more particularly to animproved form of a closely fitting cabinet for a commercial phonograph.

It is .desirable that cabinets for commercial phonographs be made smallso that they may be suitably used on the desk of the operator with apleasing appearance and with ease of portability. In order that suchcabinets may fully protect the phonograph it is important that thephonograph be completely enclosed. Whenever a phonograph is completelyenclosed by a closely fitting cabinet there are encountered difficultiesin providing a suitable cover Which will expose the phonograph forconvenient operation. This is particularly diificult with the usual formof commercial phonograph which is so arranged that it must be accessibleat its front and side portions for manipulation thereof whenever it isto be used. Access to the side portion is necessary for the purpose ofmounting a record on a suitable record support, or mandrel, and forremoving a record therefrom. Access to the front of the machine isnecessary in order to operate a translating device which moveslongitudinally of the mandrel and is adjustable by means of a controllever commonly provided therewith. In closely fitting cabinets for suchmachines there may be provided a cover for the front portion of thephonograph and a separate closure member for the side portion. The covermay then be of small and convenient form, and by a novel hingingarrangement it may be moved to a convenient open position closelyfitting the cabinet. Moreover, by suitable means coupling the cover withthe side closure member the operation of the cover between its open andclosed positions may be made to operate the side closure member betweenits respective open and closed positions.

With such a novel cabinet structure closely fitting the phonograph theremay be secured other benefits by which the operation of the phonographis safeguarded. The translating devices in commercial phonographs areadjustable, by means of the aforesaid control lever, to respectiveoperative positions wherein it engages the record for recording thereonand reproducing therefrom. This control lever is also adjustable to aneutral or an inoperative position wherein the translating device isdisengaged from the record. It is of primary importance that the controllever be in its inoperative position whenever a record is mounted on, orremoved from the mandrel, as a safeguard against damage to delicateparts of the translating device and to the record surface. Such asafeguard may very conveniently be in the form of the movable sideclosure member provided for closing the side portion of the phonograph,and for the convenient operation of the machine, it may be operated bythe control lever to suitable positions for main- 5 taining the mandrelinaccessible for operation except when the control lever is in aninoperative position.

It is therefore an object of my invention to provide a cabinetcompletely enclosing and closely 10 fitting a phonograph withoutsacrificing the ease of operation of the phonograph.

It is another object to provide means, in the form of a cabinet for aphonograph, for maintaining the correct sequence of adjustments in theoperation of a phonograph.

It is another object to provide a small and conveniently arrangedcabinet for supporting a phonograph and safeguarding its operation. I

It is another object to provide, for a commercial 20 phonograph, acabinet having a plurality of closure members, operatively connected toeach other and to a primary control means of the phonograph, forprotecting the phonograph during its operation. 25

It is another object to provide a novel structure arrangement for aphonograph cabinet whereby the appearance of the cabinet is enhanced andthe phonograph is readily accessible for servicing or repairs.

It is a still further object to provide a construction for a phonographcabinet which may be easily assembled and disassembled.

Other and allied objects will more fully appear from the followingdescription and the appended 35 claims.

In the description of my invention reference is had to the accompanyingfigures, of which:

Figure 8 is a fragmentary View taken substantially along the line 83 ofFigure 6.

Reference being had to Figures 1 and 2, there will be seen a cabinet Acontaining a phonograph B of the type commonly used commercially forrecording and reproducing dictation. The phonograph B has a base plate lwhich supports through suitable upright standards the principal parts ofthe machine. Such parts comprise a record support or mandrel 2 rotatablymounted in a standard 3 usually integral with the base 1. The spacedstandards 4 and 5 are integral with the base I and serve to support thelongitudinal rods 6 and 'l. Carried slidably upon the rods 5 and 1 is acarriage S. Pivotally connected to the carriage 8 is an arm 9 (seeFigure 6) which carries a feed nut l8 adapted to engage a feed screw H,this screw being rotatably held by the spaced standards 4 and 5. Thefeed screw H is suitably geared to the mandrel 2 so that rotation of themandrel, as by any suitable rotatory source of power, will effect arotation of the feed screw ll. Through the engagement of the feed nut H)with the feed screw 1 l a longitudinal movement, with respect to themandrel 2, is then imparted to the carriage 8. The arm 9 is suitablycoupled to a control lever I2 which is provided for controlling theengagement of the feed nut ill with the feed screw II, and for effectingother operative adjustments to the phonograph as are subsequentlydescribed.

The mandrel 2 may be of any desirable form for removably holding acylindrical record C. For convenience of operation there is usuallyprovided a mandrel which is adapted to receive a record from itsunsupported end and to hold it tightly thereon after it has reached itsoperative position. Such a mandrel may typically be of the formdescribed in the United States Patent No. 2,010,717, issued to HeinrichF. Max Gramann on August 6, 1935. This mandrel has a chuck 13 at itsoutermost end which expands in a radial direction when the recordreaches its operative position, thereby holding the record in place. Forremoving the record therefrom the mandrel is provided with a member M,at its unsupported end, which is movable inwardly in an axial directionto cause the chuck is to contract, thereby releasing the record from themandrel.

The carriage 8 carries a translating device I5 which is adjustable bymeans of the control lever l2 to an inoperative position or torespective operative positions for recording and reproducing. Whenadjusted for recording it is adapted to receive sound waves and impartmovement undulating in accordance with those waves to a stylus l6, and,when adjusted for reproducing, to create sound waves in accordance withany undulating movement imparted to a stylus I'i, such as by itsengagement with a progressive modulated groove on the record C. Thesesound waves are conveyed to, and away from, the translating device I5 bymeans of a flexible tubular member 58, or speaking tube, which carriesat its'far end a hand-piece 49 usable as a mouthpiece in recording, oras an ear-piece in reproducing.

The adjusting of the translating device [5 is done by means of thecontrol lever l2. When this lever is swung forwardly and rearwardly therespective operative adjustments of recording and reproducing areeffected, and in these operative positions the feed nut M is broughtinto engagement with the feed screw II. In the recording and reproducingpositions the styli l6 and l! are respectively brought into engagementwith the record C carried by the mandrel 2. When the control lever isshifted to a position intermediate of its respective operative positionsit places the translating device E5 in an inoperative condition anddisengages the feed nut ill from the feed screw l l. In such inoperativeposition the respective styli l6 and ll of the translating device areeach removed from contact with the rec- 0rd. The record may then befreely removed from the mandrel 2. When the control lever I2 is in anoperative position, any attempt to mount a record on the mandrel 2, orto remove one therefrom, will cause heavy strain upon delicate parts ofthe translating device and will in every case cause the record surfaceto be marred. It is therefore important that a means be provided whichwill render the mandrel inaccessible so that a record cannot be mountedthereon or removed therefrom, when the translating device is adjusted toan operative condition. In my invention I provide such means as afeature of my novel and improved closely fitting cabinet structure.

It is to be understood that although I illustrate my cabinet with asimple means for obstructing a single manipulation in the operation ofthe phonograph, except when a primary control of the phonograph is soadjusted to safely permit such first manipulation, my invention alsocontemplates the provision of a cabinet having a plurality of means forrequiring the proper sequence in the operative manipulations, oradjustments, of a phonograph whenever a plurality of such adjustmentsare required in the operation of the machine. This, however, is only oneof several features of my improved phonograph cabinet, as my invention,in its broader aspects, contemplates a generally improved and closelyfitting cabinet structure providing full protection to a phonograph andeasy access thereto for its safe and convenient operation. Othercardinal features of my cabinet rest in a novel structural arrangementhaving a pleasing appearance and providing a high degree of portabilityand easy access to the phonograph for its servicing or repair.

The frame of my cabinet comprises the respective left and right sidesections 58 and 19 forming the central portions of the respective sidewalls of the cabinet. These sections may be suitably cast in anydesirable form, but I prefer that they be arch-shaped and have anincreased wall thickness near the rim thereof such as is shown inFigure 1. They may a so be desirably provided with recesses at theirbottom central portions such as the recess l9 for the section l9, whichrecesses aid in the lifting of the cabinet from any support providedtherefor. The side sections 38 and iii are rigidly connected together bymeans of the respective front and rear tie bars 2t and 2!. Forconnecting the tie bars to the side sections there are provided lugs inthe rear and front portions of the respective sections, such as the lug22 on the rear portion of the right hand section [9 shown in Figures 3,4 and 5. The respective lugs have apertures through which pass suitablescrews that thread into the respective tie bars, such as the screw 23for holding the lug 22 to the rear tie bar 2|. By this arrangement theside sections l8 and I9 and the tie bars 23 and 2| form the frame of thecabinet and the supporting structure for the phonograph B. The bottom ofthe cabinet may be closed in any desirable manner.

For securing the phonograph B to the aforesaid supporting structurethere are provided in the respective left and right side sections i8 andI9 suitable front and rear bosses such as 24 and 25 for the left sidesection [8, and 26 and 21 for the right side section I9. The base plateI of the phonograph is provided with downwardly extending corner posts28 and 23 on the respective front and rear portions of the lefthandside, and with the posts 33 and 3| on the respective front and rearportions of the right-hand side. The posts 28 and 23 are respectivelyconnected at their lower ends to the bosses 24 and 25, as by the screws24 and 25. The posts 30 and 3| are similarly secured to the respectivebosses 26 and 21, as by the screws 23 and 21'. By this means the baseplate I is rigidly connected to the frame of the cabinet A. Thephonograph B which is supported by the base plate I is disposed thereonin such an arrangement as to bring the axis of the mandrel 2 inalignment with the vertical center lines of the side sections I8 and [9.

In my cabinet structure the front and rear portions are respectivelyenclosed by means of the closure sections 32 and 33. These closuresections have inwardly curving lower portions which rest upon therespective tie bars 23 and 2 These sections may conform to, or lapslightly inwardly of, the respective side sections I8 and !9 so as tocomplete the enclosure of the ends of the cabinet. They may be of anysuitable form for give ing a pleasing appearance to the cabinet such,for example, as is illustrated in Figures 1 and 2. They may berespectively fabricated from sheet metal by any suitable means, such asby stamp ings. The rear section 33 is provided with the respective leftand right side portions 33 and 33" so that it completes the enclosure ofthe rear half of the cabinet. The front section 32 completes theenclosure of the lower front portion of the cabinet, the remainingportion of the cabinet being enclosed by a cover 34 which is adapted toswing upwardly to a position above the rear closure section 33 and toconform to the upper portion thereof. For this reason the left and rightside portions 33' and 33" of the rear closure section 33 are extendedinto the front half of the cabinet and provided along their edges 34'with a curvature which is identical to the curvature of that upperportion of the section 33 to which the cover 34 conforms when it res-tsin its open position.

The front and rear closure sections 32 and 33 are each detachablyconnected to the frame of the cabinet to provide easy access to thephonograph for its servicing or repairs. For holding the rear closuresection 33 in place it is provided near the bottom thereof with therespective left and right side arms 35 and 36 (see Figure 6) which aresuitably secured thereto as by welding. The forward portions of therespective arms 35 and 33 are provided with downwardly extendingnotches, such as 33 for the arm 35, which are adapted to engage with therespective outwardly extending pins 31 and 38 provided on the respectivebosses 25 and 21. The closure section 33 is suitably secured to theframe of the cabinet at its upper end by means of the respective screws39 and 40, shown in Figures 1 and 4 respectively, which thread into thearched rim portions of the side sections l8 and IQ for respectivelyholding the left side portion 33 to the section l8 and the right sideportion 33" to the section l3. Thus with the removal of the screws 39and 43 the rear closure section 33 tips backwardly for easy detachmentfrom the frame of the cabinet.

For detachably connecting the front closure section 32 to the frame ofthe cabinet, this section is provided with respective left and rightside arms, such as the arm 4! on the righthand side, which arms aresuitably secured thereto as by welding. These left and right side armsare in all respects similar to the arms 35 and 36 of the rear closuresection 33, and are adapted to engage with the respective outwardlyextending pins 42 and 63 provided on the respective bosses 24 and 26.This closure section 32 is provided with forwardly extending ears at itsupper left and right sides, such as the ear 43 on the righthand sideshown in Figure 2. Extending respectively through these cars, as bysuitable apertures provided therein, are the screws 45 and 46 whichthread into the respective left and right side sections l8 and [9 forholding the upper portion of the closure section 32 in place. Thus, thefront closure section 32, as in the case of the rear closure section 33,is readily detachable from the frame of the cabinet.

As shown in Figures 1 and 2 the front closure section 32 extendsforwardly at the front portion of the phonograph B to provide acompartment 41 which serves for conveniently holding the tubular member48 and handpiece 49, as during periods of non-use. During the use of thephonograph the tube 43 may be left to extend outwardly of the cabinet.In this case there may be provided a suitable member, not shown, whichmay be moved outwardly of the cabinet for supporting the handpiece 43during inoperative periods in the use of the machine. When the cabinet Ais to be closed the tube may be disposed within the compartment 31lengthwise thereof and the handpiece 49 may be disposed in any desirableupright position such, for example, as is shown in Figures 1 and 2.

In order to permit access to the record support or mandrel 2 forinstalling a record thereon, or removing a record therefrom, there isprovided an opening 53, preferably circular in form, in the upper archedportion of the righthand side section 19. I prefer that the center ofthe opening 53 coincide with the axis of the mandrel 2 and that thediameter of the opening be suitably,

larger than the diameter of the record C so that the record may beconveniently installed on or removed from the mandrel 2. For thisopening there is provided a side closure member 56 having an uppercircular portion conforming to the opening 52 and movable between openclosed positions. The closure member may be moved in any desirablemanner but I preferably have it slide upwardly and downwardly in thegrooves 32 provided in the vertical rim portion of the side section l9.These grooves are disposed in the rim adjacent to the center panelportion 53 so that the closure member 51 fits closely thereto. In myinvention the movement of the closure member 3i is controlled both bythe cover 34 and the control lever l 2 in a novel manner forfacilitating and safeguarding the operation of the phonograph.

For completing the enclosure of the cabinet there is provided the cover34 having a handle 54. This cover is adapted, when in a closed position,to form an upward extension of the walls of the front closure section 32and to conform with the edges 34 of the rear closure section 33. Thegeneral shape of the cover 34 may be such as to give the cabinet asymmetrical appearance from the end when the cover is in a closedposition, such, for example, as is shown in Figure 2. The opening 50 ismade continuous with the front opening of the cabinet in order toprovide the operator with full visibility of the mandrel 2, therebyfacilitating the mounting of a record thereon or its removal therefrom.In order to provide such continuity a segment 55 of the arched rimportion of the side section I9 is broken away; it may be secured to thecover 34, as shown in Figure 1, so that it comes into a positioncompleting the arch of the section I9 when the cover is in a closedposition. On the corresponding portion of the opposite side the coverlaps inwardly of the forward arched portion of the left side section l8.

The cover 34 swings upwardly in a novel manner to a position above thecabinet wherein it conforms with the upper portion of the rear closuresection 33 as shown in Figure 1. The pivoting arrangement for securingsuch upward swinging movement comprises the respective left and rightside levers 55 and 51 pivoted on studs secured, as by riveting orwelding, to the respective left and right side walls of the rear closuresection 33, such as the pivot stud 58 for the right hand side. The cover34 is provided with L-shaped side extensions 53 and 60 on its respectiveleft and right sides, which extensions are pivotally connected at pointssuitably in from the ends thereof to the respective side levers 56 and51 as by the pivots 56' and 51'.

For guiding the movement of the cover 35 between its open and closedpositions there are provided the respective left and right tracks GI and62 which are secured at their respective rear end portions 6| and 82, tothe respective left and right side walls 33 and 33 of the rear closuresection 33, as by welding. These respective rear end portions aresuitably offset so that the respective tracks 6| and 62 may extend alongthe sidewalls 33 and 33" with suitable clearance. These tracks curvedownwardly substantially in an arc about the pivot studs provided forconnecting the side levers 5G and 57 to the side walls of the rearclosure section 33, such as the pivot stud 58 on the right-hand side.There are secured at the ends of the side extensions 59 and Gil inwardlyextending pins 63 and 64 which carry the respective rollers 65 and 66.These rollers ride on the respective tracks BI and 62 for guiding themovement of the cover 34. In order to maintain the rollers in engagementwith their respective tracks there are provided the tension springs 61and 53 which respectively connect the pin 33 with the lower end of theside lever 56 and the pin 64 with the lower end of the side lever 57.For this reason the side levers 56 and 57 have their lower end portionsbent inwardly and respectively provided with suitable apertures throughwhich may hook the respective springs 61 and 68, such as the end portion57" for the lever 51 At the rear of the respective tracks 6| and 62there are provided suitable notches 68 and 10 defining the open positionof the cover 34, as shown in Figures 1 and 2 respectively. As the covermoves downwardly from such open position it will first tilt forwardlyabout the pivots 56 and 51' as the rollers 65 and 66 move out of therespective notches 69 and 10. Such initial forward tilting movement ofthe cover as it moves from its open position prevents any rubbingbetween the cover and the upper portion of the rear closure section 33.Likewise, in the upward movement of the cover it will swing above therear closure section with suitable clearance and then tilt rearwardly toits aforesaid open position as the rollers 65 and 66 register with therespective notches 69 and 10. By this novel hinging arrangement of thecover 34 I am enabled to move the cover to an open position closelyfitting the cabinet and yet expose the entire front portion of thephonograph for its convenient operation with the use of a very small andshallow cover.

In the cabinet of my invention the side closure member 5| is coupled tothe cover 34 so that upward and downward movements of the cover 34 willelfect respective downward and upward movements of the side closuremember 5|. The closure member 5| is preferably also suitably coupled tothe control lever I2 so that the member 5| will move to a positionobstructing the accessibility of the mandrel 2 whenever the controllever is moved to an operative position. By this novel arrangement Isecure the following desirable actions: With the control lever I2 in aninoperative position, as the cover 34 is moved between its. open andclosed positions the side closure member 5| is moved between itsrespective fully open and closed positions. With the control lever |2 inan operative position, as the cover 34 is moved between its closed andopen positions the side closure member 5| is respectively moved betweenits closed and a suitable intermediate position. With the cover 34 in anopen position, as the control lever I2 is moved between its operativeand inoperative positions the side closure member 5| is moved betweenits respec tive intermediate and fully open positions. Thus, my cabinetcompletely encloses the phonograph and yet provides ready access theretofor its convenient operation, such access being controlled in a mannerto safeguard the phonograph as it is used. The mechanism coupling thecover 34 and control lever l2 with the closure member 5| to effect suchresultsv will now be described in detail.

The mechanism coupling the cover 34 with the closure member 5| comprisesa vertically disposed link member 1| shown clearly in Figures 3 and 6.

This link member is pivotally connected at its upper end, as by thepivot 12, to the lower end of the side lever 51. The lower end of thelink has an enlarged portion 1| within which is provided a cam slot 73.This slot is preferably are shaped about the pivot 72 at its forward andrearward end portions, and is curved upwardly from its forward end in asuitable manner, such as is shown in. Figure 3. At the lower righthandside of the cabinet there is provided a side arm 74 which is pivoted tothe righthand arm 36 provided for holding the rear closure section 33 inplace. The arm 14 carries an inwardly extending pin or roller 15 at aposition approximately midway of its ends. The roller 15 registers withthe cam slot 13 and may be normally retained in the forward end of thisslot by reason of a light tension spring 16 connected between the lowerend portion 1| of the link member El and the rear portion of the arm 36.The forward end portion 14 of the arm'14 is provided with a longitudinalslot H. In this slot there slidably engages an inwardly extending pin I8secured to the lower mid-portion of the closure member 5|. Downward orclosing movement of the cover 34 rotates the side lever 51 in acounterclockwise direction. This causes the link member H to be raised,and therefore the arm I4 is rotated in a clockwise direction to move theclosure member 5i upwardly. The length of the various members comprisingthis coupling mechanism, and the location of the various pivots, arechosen so that the closure member 5! is in its open or most downwardposition when the cover 34 is fully open, and so that the member 5| has:reached its closed or most upward position when the cover 34 is fullyclosed. It is. thus obvious that a movement of the cover 34 between itsopen and closed positions effects a movement of the closure member 5|between its respective open and closed positions.

As aforementioned, with the cover 34 in its open position, as thecontrol lever I2 is moved to either of its operative positions, the sideclosure member Si is moved upwardly to a partially closed position,such, for example, as shown in Figure 1. Normally the control lever I2pivots about the longitudinal rod 6 and slides thereon as the carriage 8moves: longitudinally of the mandrel 2. For coupling the control leverI2 with the closure member 5|, the control lever I2 is keyed or splinedto the rod 9 as. shown in Figure 3. This spline connection may comprisea screw I9 threading into the hub: I2 of the control lever I2 andengaging with a longitudinal slot or groove I5 cut into the rod 6. Thecontrol lever i2 is then rotatably coupled to the rod 6 and may slidelongitudinally thereon, the rod 6 being pivotally supported at its endsin the left and right standards 4 and 5 in any suitable manner. As maybe seen clearly in Figures 3, 6 and '7 a cam plate 80 is provided on therighthand end of the rod 6. For securing the cam plate thereon the endportion of the rod 8 is provided with a reduced diameter portion. 8" toform a shoulder on the rod. The cam plate is apertured to fit theportion 6 and is provided with a tongue 8I engaging with the groove 6,the cam plate being suitably held against the shoulder above-mentionedby means of a screw 82 threading lengthwise into the rod 6.

The link member II extends upwardly of the pivot I2 and is provided atthe upper end thereof with a pin. or roller 83-which registers with thesurface of the cam plate 80. The cam plate 80 has a central concavelyshaped portion 84, and is positioned on the rod 8 with respect to thecontrol lever I2 so that the roller 83 engages with the central point ofthe concavely shaped portion 84 when this lever is in a central orinoperative position and the cover 34 is in an. open. position, such asis shown in Figure 3. As the control lever I2 is: moved to either of itsoperative positions such, for example, as its forward position forrecording and its rearward position for reproducing, the cam plate 88,by its engagement with the roller 83, will rotate the link member II ina clockwise direction about its: pivot I2. By reason of the upwardlycurving cam slot I3, provided inv the lower end portion II of the linkH, a clockwise rotation of the link member II produces a clockwiserotation of the arm. I4 to move the closure member 5| upwardly to aposition such as shown in Figure 1. If the control lever I2 is movedforwardly to its usual position for recording the mechanism coupling thecontrol lever to the closure member 5| takes the position shown in.Figure 6. If the control lever I2 is moved rearwardly to its usualposition for reproducing the mechanism takes the position shown inFigure 7. In each case the closure member 5I is moved upwardly to apartially closed position so as to make the mandrel inaccessible formounting a record thereon, or removing a record therefrom.

In order that a return movement of the control lever I2 from either ofits operative positions to its inoperative position may effect adownward movement of the closure member 5| to its fully open position,the outline of the cam 80 is closed, except over its central portion, bymeans of a guide member 85 secured to the cam plate 80 by the rivets Theguide member 85 is in the form of a plate having inwardly extending ribs88 and 8! which conform in curvature to that portion of the cam 80towhich they are adjacent. The roller I5 thus registers with the inwardsurface of the ribs 86 and 8! as the control lever is swung to itsinoperative position from either of its operative positions, therebyimparting a counterclockwise rotation to the link member II. The cam 80is, however, not closed over its end portions 88 and 89, and over thecentral portion 84, in order that the roller I5 may be free to leave thecam at these points, such as is necessary whenever the cover 34 is swungdownwardly to a closed position. The end portions 88 and 89 and thecentral portion 84 of the cam 80 are substantially are shaped about thepivoting axis of the cam 89 in order that the roller I5 will not tend toleave the cam 80 at these positions except as an incident of downwardmovement of the cover.

It will be observed from Figure 3 that the side closure member 5i restsin its open position when the cover 34 is in an open position and theroller I5 of the pivoted arm I4 registers with the forward end of thecam slot I3. With the roller I5 maintaining this forward position in thecam slot I3, a movement of the cover 34 to its closed position willeffect a movement of the closure member 5| to its fully closed position.Such closing movement of the cover 34 causes the roller 83 of the linkmember II to move through the locus 9| to a position 92 shown in Figure3. However, when the cover 34 is open and the control lever I2 is ineither of its operative positions the roller 15 registers with the rearend of the cam slot I3, and the roller 83 has the position indicated at93. Therefore, in order to provide a free closing of the cover 34 whenthe control lever is in an operative position, some means must beprovided for rotating the link member II in a counterclockwise directionsimultaneously with the closing of the cover so that the roller I5 willmove forwardly in the cam slot I3 and register with the forward endthereof when the cover reaches its closed position. The roller 83 willthen have moved through a locus to a position coinciding with theposition 92. For eiTecting such counterclockwise rotation of the linkmember II I provide a suitably shaped stationary guide member 94 whichis secured to the righthand side wall 33" of the rear closure section33, as by rivets or welding. As the cover 34 is closed with the controllever I2 in either of its operative positions, the roller 83 leaves thecam 89 and registers with the guide member 94 which guides it to theposition 92.

If the cover 34 is opened when the control lever I2 is in either of itsoperative positions, the link member II must be rotated in a clockwisedirection with such opening movement so that the roller 15 will registerwith the rearward end of the cam slot 13 when the cover reaches its openposition. The roller 83 will then have to return through a suitablelocus from the position 92 to the position 93. When the control lever I2is in its rearward operative position the roller may be easily guided tothe position 93 by an extension of the upward end portion 38 of the cam89, as is clearly shown in Figure '7. For guiding the roller 83 to theposition 83 when the control lever is in its forward operative positionI provide a suitably shaped extension ill on the lower end portion ofthe rib 8?, as is shown in Figure 6.

Although I have described a preferred embodiment of my invention it isto be understood that the same is subject to many changes andmodifications without departure from the scope of my invention which Inow undertake to express according to the followirr claims.

I claim:

1.
